Why does my Mercedes shake when idling? π
Sitting at the lights and feeling a vibration through the steering wheel or seats? A rough or shaky idle can be a sign that your Mercedes isn't running as smoothly as it should.
There are a few possible causes, including:
β’ Worn engine or transmission mounts
β’ Spark plug or ignition issues
β’ Air or fuel delivery problems
Sometimes the cause can be simple, but it's worth having it checked, particularly if the shaking is new, getting worse, or accompanied by a warning light.
At Balmain Automotive, we specialise in Mercedes-Benz and European vehicle servicing and repairs, using diagnostics to help find the cause of the problem.
If your Mercedes looks smooth but isn't feeling as smooth as it used to, give us a call and we'll take a look: (02) 9810 6326
